Filter improves safety and performance

Parker Hannifin has developed an innovative duplex filter system designed to improve both safety and filtration performance in a wide range of industrial applications.

The new EADPF iprotect filter incorporates Parker's hydraulic solenoid valve technology, making it possible to switch between filters remotely, and optimising productivity as a result.

While conventional duplex filters require the main duplex valve and equalizing line to be manually operated, the new Parker EADPF iprotect® filter improves safety and efficiency by making remote operation possible. Furthermore, this process can be fully automated, cutting maintenance requirements and minimising machine downtime as a result.

When one filter element becomes contaminated, the in-built filter condition indicator sends a signal to the duplex valve unit, telling it to switch to the other filter with a clean element. This enables effective filtration to continue without the need for manual intervention.

At the same time, a warning signal is provided to the local overall system controller, informing the operator that the contaminated filter element requires replacement. Routine maintenance can then be carried out at the most convenient time.
